I'd say this knocked down the gnats a bit but they are not gone. Granted I'm growing in a greenhouse which is paradise for gnats. I've used Gnatrol in the past and with that product I can achieve complete control when combined with an oil spray such as SuffoilX. This year I tried the WDG3000 but, have used the entire bag so far this season, use it every watering and I still have gnats. All through veg the flying gnats were kept at bay with the sprays, now in flower can't spray and doing what I can to knock down the flying gnats by just spraying the soil surface with Neem, tweetmint, and EM5. Seems like you would get the same results using something much cheaper like Mosquito bits or Microbe-lift, going back to the Gnatrol for now.
The manufacturer that we use invented the entire process. They are responsible for making the lower concentration products such as Mosquito Dunk and liquids like Microbe Lift etc. So it's basically a game of how to buy from and we felt it was best to go direct to the source. Gnatrol same thing. SuffoilX is petroleum based. One thing that helps is to understand that the way the bacteria works, they cannot build an immunity, so if there are still gnats after diligent soil treatment, there is another location unnoticed, possibly under your containers? Somewhere still moist and dark and not treated would provide a way for them to continue. I really hope this helps, I want you to have confidence in using this product.

I think it’s a little pricey for its effectiveness. Has only knocked down the gnats. Been treating for 10 days.
I get it! These biologicals can be pricey. Most expensive is the product that doesn't work. I promise this one works and will provide results but it takes up to 14 days based on the Fungus gnat lifecycle. We guarantee the product and hope that you have since kept up and seen the results. Another factor is these dang gnats will start going to other damp and dark places like underneath your pot, so be sure to treat any area where they can breed.
